What are the solutions to cos(2theta)=-1/2 in the interval [0,2pi)

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

what shape is

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
